Table - best surf conditions forecast for Jaconé over the next 16 days.
Alright, let’s break it down in feet, miles per hour, and Fahrenheit.
Jaconé starts out ugly. Wednesday the 8th is a total no-go – onshore wind, junk surf, and low energy. Not worth your time.
Thursday morning, July 9th is a standout. We’re looking at 5ft SSW swell with a 9-second period, and the wind goes glassy. That means clean, fun waves with moderate energy. This is the dawn patrol you want to make.
Friday the 10th morning brings a clean 3ft SE groundswell with a long 14-second period. Off-shore NE wind at 6 mph will keep the faces smooth. It’s smaller but the long period will give you some sweet, peeling lines.
Saturday the 11th gets choppy with cross-onshore wind. Sunday the 12th morning is glassy again with 3ft SE swell – clean and rideable.
Monday July 13th morning has a bigger pulse: 5ft S swell at 13 seconds, combined energy of 861. More power, but the wind is onshore. It’s a tough call.
Tuesday the 14th sees the swell jump to 7ft in the morning and 8ft in the afternoon, with a 10-second period and onshore wind. That’s expert-only, heavy water. Combined energy of 1191 says there’s serious juice.
Wednesday July 15th morning is another winner: off-shore ENE wind at 9 mph, 5ft S swell at 12 seconds, and combined energy of 889. Clean, powerful, well-shaped. A top session for confident surfers.
Thursday July 16th morning is also excellent: 5ft S swell, 12-second period, and glassy off-shore NNE wind. Clean lines with solid energy.
The second week brings consistent but smaller SE swells, from 3ft down to 3ft, with clean off-shore winds and light breezes. Mellow, fun, and plenty of waves for cruising.
Best bets: Thursday the 9th and Wednesday the 15th mornings. Clean, good size, and the wind on your side.
Crowds can show up, so get in early.
Rusty’s done. Catch ya.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
